(553a) Evaluation of a Bench-Scale 3-Bed PSA Cycle Utilizing a Modified 13X Zeolite at the National Carbon Capture Center (NCCC)

The objective of this multidisciplinary project is to develop a transformational molecular layer deposition (MLD) sorbent based on 13X zeolite that is then integrated into a pressure swing adsorption (PSA) cycle for CO₂ capture from a pulverized coal power plant. The project team is comprised of researchers from UB, RPI, USC, Gas Technology Institute (GTI), Trimeric Corporation (Trimeric), and the National Carbon Capture Center (NCCC). The program uses the unique expertise of each team member, with UB/RPI doing transformational sorbent development, USC doing innovational PSA process integration with sorbents, GTI doing field testing processing and engineering, and Trimeric performing technoeconomic analyses (TEA). The goal is to achieve DOE cost and performance targets of 95% CO₂ purity and 90% CO₂ recovery with no more than 10 ppm of O₂ in the CO₂ product based on full scale simulation and bench-scale testing. This presentation will present some of the latest results from this project, including full scall PSA process modeling with both MLD and 13X zeolite sorbents, design and construction of a 3-bed PSA test rig, and evaluation of the performance of the 3-bed PSA cycle at the NCCC when utilizing the MLD sorbent.
